Continuous Vacuum

The continuous vacuum “CV” furnace essentially transforms a batch vacuum furnace into a straight through furnace.  Work is no longer processed into and out from the same side – rather work is loaded into the entry side and unloaded from the exit side of the furnace.  Modules consist of load/evacuation chambers, preheat and high heat chambers, multiple heat position chambers, and quench (oil and/or pressurized gas) chambers.

Small batches are indexed in a continuous fashion making this style furnace highly productive in processes that range from annealing, brazing, carburizing, sintering, to hardening.  Processing of smaller lots allows for tight temperature uniformity within the working area to provide near identical thermal profiles within the work lot – center to edge.  With the continuous vacuum furnace, the heat chamber is not exposed to room air conditions nor is it thermally cycled.  It remains hot and under vacuum making for a highly efficient and pure system that enhances part quality.

Designs of the modular “CV” vacuum furnace can produce up to 1500 lbs/hr (680 kg/hr) with temperature capabilities to 2600°F (1427°C).
